After a string of scandals and controversies in his three-year term in office, UK Prime Minister Boris Johnson on Thursday agreed to step down from the post of the Conservative Party leader. The move is set to end an unprecedented political crisis and trigger an election for a Tory leader who will go on to become the new premier. Johnson, 58, will remain in charge at 10 Downing Street until the process of electing a new leader is completed by the time of the Conservative Party conference, scheduled for October. He is expected to formally announce his resignation and address the nation later on Thursday.
